SerialNo.- 425,441.

This invention relates to improvements in concealed heating means and the principal object of the invention is to provide a complete heating unit including a cabinet which can be entirely recessed and concealed entirely within a wall and covered with a panel which harmonizes -with the interior woodwork and finish of the room and is removable Without tools and is provided with selfclosing doors permitting access to valves and fastening means Within the cabinet.

A further object is to provide a complete self-contained heating unit which can be manufactured entirely in the factory and which will have its parts so related and adjustable that it can be adapted to the irregularities and variable factors in building construction without the necessity of individu- A ally cutting and fitting the structure to adapt it to a particular installation.

The heating element B may be of a suitable type for the purpose. The radiator of the type disclosed in Patent No. 1,775,257,

issued September 25, 1930, is especially adapted to the purposes of the present invention, because of its compactness, lightness of weight and high eiiiciency. Radiators of this type can, for given capacity, be made narrow enough to occupy less space than the space within the confines of thev usual or standard wall construction of buildings, hence they are particularly adaptable to socalled invisible or concealed heating units. These radiators or heating elements comprise in general a core member 1 for the passage of steam or hot water, and a plurality of thin highly conductive ns or plates '2 mounted on said core in intimate association therewith and arranged in parallel with their outer edges 3 turned at right angles and engaged with the next adjacent fins to provide a plurality of passages 4 through which the air circulates in the process of heating-said air, as shown more clearly in Figs. 2 and 7.

The radiator is horizontally positioned in the ing 7 and return piping 8. A hand valve 9` is usually connected in the inlet end of the radiator andtrap 10 in the outlet or return end, Fig. 2.

In heating systems in buildings, the laypout of pi ing, while located within the confines o the walls, is varied greatly in accordance with the construction of buildings layout is illustrated in Fig. 2, in which theA inlet pi e 7 and the return pipe 8 are both dispose horizontally and lead into the cabinet through the same end wall. The return pipe 8 extends clear across the cabinet beneath the radiator to the return end of the radiator. It is just as usual, however, to enter the inlet pipe horizontally through one end wall Aof the cabinet and the return pipe through the opposite end wall, or to extend both pipes vertically through the floor to the radiator at the respective ends thereof.

The arrangement of piping constitutes no part of this invention, but in order to accommodate the heating unit-to these various piping conditions, the structure is arranged, as

will hereinafter appear, for adjustment with respect to any particular piping layout, with- -out the necessity of cutting and fitting the individual unit. This makes it possible to manufacture the heating units complete in the factory and to ship them ready for installation.

The housing or cabinet A is preferably made of sheet metal substantially rectangular in shape and provided with a. rearcwall 15, a top wall 16, and end walls 17. he lower edges of the end walls are turned inwardly to form flanges 18 for fastening the cabinet ,to the floor or framing of the wall within the recess, and to strengthen the lower edges of the walls.

The cabinet is comparatively shallow in depth to correspond to the depth of the recess in the wall in which it is positioned, and the front edges 19 of the top and end walls are intended to be flush with the plaster line of the wall or with the plane of whatever material is used for finishing the wall. In fact, these front edges can be so positioned that they will serve as grounds to guide the plasterer in the application of the finishing or final face coat to the wall.

Since the `thickness of walls varies considerably with the character of the materials used, means are provided by which the position of the cabinet within the recess may be readily adjusted to conform to the wall thickness. In the drawings, the wall structure is indicated conventionally as comprising the outer wall construction 22, aud lath and plaster covering 20 supported by the usual studding 21. The recess D is formed in the space defined by this studding between the wall covering 20 and the outer wall 22, Figs. 5, 6, and The upper margin of the recess is defined by a suitable header 23 secured in position horizontally between the vertical studding which define the end margins of the recess.

The cabinet or housing is installed in the recess D and its position within the recess is determined by adjustable angle or flange members on the end walls 17 and the top wall 16 of the cabinet. These angle members have one of their flanges 24 flat against the walls of the cabinet and their other flanges 25 extending outwardly at right angles to the cabinet wall surfaces. They are clamped in position by the fastening screws and nuts 26 which extend through these flanges 24 and through the walls of the cabinet. The openings in the flan es 24 for the fastening screws are elongate slots 27 which permit of considerable relative adjustment in and out ofthe flanges with respect to the cabinet.

In installing the structure, the flanges are placed against the studding and headers and the angle members adjusted on the cabinet until the forward edges 19 of the cabinet project from the plane of the studding and header a distance corresponding to the desired thickness of the Wall material 20, as shown more clearly in Figs. 2, 5, 6, and 7. T he flanges are interchangeable and reversible, so that in the event that the thickness of the wall material 2O is greater than the range of adjustment of the flanges in the relation in which the angle members are shown in Fig. 7, the angle members may be reversed to bring their flanges 25 closer to the rear wall of the cabinet. This will permit the cabinet to be extended a greater distance outwardly from the plane of the studding. This coridition arises where brick or tile is used for wall covering material, thus making the wall several inches thick beyond the studding. lVhere metal lathingis used in the wall covering, the flanges 25 also serve as anchors to which the edges of the latliing surrounding the recess may be secured. The advantage of this construction is that the range of adjustment permitted by the adjustable fianges is sumciently great to accommodate any of the various types of wall covering used inbuilding construction, without the necessity for cutting and fitting the cabinet. In other words, by means of this adjustable structure, the front edges 19 of the cabinet can always be positioned flush'with the outer face of the wall, regardless of the thickness of said Wall.

In order to accommodate the cabinet to the various piping layouts found in building construction, the end walls 17 ai'e provided with a plurality of knockout portions 30 which are distributed over an area of the end dwalls within which the piping is likely to be brought into the cabinet. These knock-- out portions are of well known construction and consist in wea-kening circular portions of the metal, which permits them to be removed b v a slight blow of a hammer and which provides a clean-cut circular opening. A sufficient number of these knockouts are provided to accommodate any position to which the cabinet is adjusted. The flanges 24 of the adjustable angle members are cut away at 31, Fig. 5, around the area of the knockouts so as not to interfere with the pipinet by means` of vertically disposed partitions 35which are positioned at the ends of the radiator and which have cut-out portions forming horizontal shoulders 36, Fig. 3, upon which the inlet and outlet nipples 5 and 6 of the radiator rest. These partitions have right angled vertical flanges 37 on their rear edges, which are slidably mounted vertically in guide clips 38, Fig. 2, struck up from the rear wall l5 of the cabinet and bent over to embrace said flanges. The lower ends of the partitions rest on the framing of the wall substantially at the floor line and support the radiator at the proper height within the cabithe cabinet may be adjusted by placing blocks of suitable thickness beneath the lower ends of the partitions. The so-called leveling of radiators for draining purposes may also be accomplished bv blocking up one end of the radiator slightly higher at its inlet end. The vertical .sliding adjustment of the partitions also serves another purpose. In the event that the piping is brought vertically into the cabinet from below, and connections therewith have to be made close to the floor, .the partitions may be raised vertically to provide sufficient clearance for swinging wrenches or other tools used in making the pipe connections.

The length of the cabinet and the radiator is so proportioned that there is sufficient space between the partitions 35 and the adjacent end walls of the cabinet to provide room for the valves, traps, and other fittings; The end chambers thus formed between the partitions and the Walls of .the cabinet are ventilated to prevent interference. with the operation of the usual thermostatic steam traps l0, by circulating sufficient air through these chambers. This ventilation is accomplished by elongated slots or openings 40 in the partitions 35 which form ports communieating with the front cool air inlet of the cabinet and through which air can enter the end chambers and circulate upward around the steam traps. These openings are large enough so that the return pipe 8 can be inserted therethrough in the event that the piping layout requires the return pipe to be extended across beneath the radiator to the opposite end of the cabinet, as indicated in Fig. 2. If it is desirable to conceal the return pipe 8, it may be positioned lower and closer to the floor and extended through a quarter-round conduit 41 which extends between the partitions 35. This conduit is se,

cured at its ends to the partitions 35, and, in addition to concealing the return pipe 8, it also acts to hold the partitions 35 in rigid relation to each other. The conduit ma also be used for concealin electric bell an ytelephone wires if desire The recess D in the wall and the heating unit are covered by a panel C which may be of any suitable shape for the purpose, and` which may be given in suitable ornamentation to harmonize with the interior of the room. This panel is comparatively thin so as not to project into the room sufficiently to occupy any appreciable floor space. It is preferably formed of sheet metal with its top and side edges 45 bent inwardly at right angles to provide a finished edge for the panel and to engage the outerface of the Wall as snugly aspossible. The panel may be secured in position in any suitable manner for the purpose, but for appearances sake it is U Y u advisable to conceal these fastening means. net. The relative height of the radiator 1n Figs. 6 and 7 show fastening or anchoring means for the cover panel. This consists of hooks 46 adapted to engage in holes 47 formed in flanges 48 on the top edges of the partitions 35. A plurality of these holes may be provided to accommodate any irregularities there may be in the relation between the heating unit cabinet and the wall. The hooks are conveniently hinged to small brackets 48 which .are fastened, preferably by welding, to the inner face of the panel.

When the panel is in position it forms, with the cabinet, a chamber or duct by which the air is conducted upwardly through the radiator. The lower edge of the panel adjacent the floor line is cut out to form an inlet opening 49 for the admission of cooler air from the room into the cabinet below the radiator. In likemanner, the upper portion of the panel is provided with an opening or port 50 which forms an outlet for the heated air above the radiator. The air inlet opening 4l at the bottom of the structure is approximately the `same length asthe space between the inner partitions 35. Since the partitions 35 are positioned close to the ends of the radiator, the duct formed between them and the rear wall of the cabinet and the cover panel insures the circulation of all the incoming air through the radiator,

`and prevents the by-passing of any air around the radiator, except the slight amount which circulates through the Ventilating slots 40 1n the partitions. The outlet 50 may prefera'bly be greater in area than the inlet 49, so as not to offer any resistance to the out- 1 flow of heated air from the cabinet chamber above the radiator. This outlet opening may be provided, if desired, with a suitable ornamental grill 51, Fig. l.

It is not intended that the panel, after having once been fastened in place, should be removed unless repairs are necessary. It is desirable, however, that access be permitted to the interior of the cabinet for such purposes as manipulating the hand valve 9. For

this purpose, I provide openings through which convenient access may be gained to the interior of the cabinet. These openings are l preferably located in the upper portion of 54 the panel above each end chambercontaining the valves and fittings. In the structure shown in Fig. 1,. the openings are located at opposite ends of the outlet and are conformed in shape and appearance to the harmonious d-esign of the panel. However, since they perform no function with reference to the heating operations of the structure, I prefer to maintain these openings closed by means of doors 52 which are hinged at 53 at their upper ends to swing inwardly. Thus, when it is desired to gain access to the interior ofthe cabinet for such purposes as manipulating the hand valves, the person may swing the door inwardly and insert his arm through the opening. Access-is also gained to the panel hooks .wh-en the panel is to be removed. On theirfinner sides, the doors are provided with suitable cou-nterweights 54 which' automatically return the access doors to closed positionzwhen the arm is removed. These doors may be given `the appearance of panels conforming to the design ofthe cover panel in suchfmanner as not tok indicate the presence of the access open-ings.

On accountfojf the fact that in astructure of this character it is difficult to provide a tight joint between-the edge of the. panel and the wallv surface due to the irregularities of the wall, leakage of hot air would occur around the edge of the panel adjacent the wall and cause streaks, which, of course, mar the appearance of the wall. To guard against any-leakage of this character, a channel is provided along the front edge of the top wall of the cabinet and the upper edge portions of the side Walls of the cabinet. This is accomplished by metal strips 55 which are fastened along the inner surface of the top and end Walls of the cabinet and arranged withtheirouter edge portions offset, Figs. 6 and 7, to'space them from tne cabinet walls andthus form channels or grooves between the cabinet r`walls and the strips. The strips are secured to the cabinet walls, preferably by welding,i'and vare provided with holes through which the'fastening screws 26 for the adjustable angle members are inserted. In additionto this, .al tongue 57 is fastened tothe innenfacefofthe panel B in position toenterfthe marginal groove of the cabinet when the panel vis placed imposition. This tongue is of considerable width and extends to 'a` con "dei-'abledeptlilinto thel marginal i together with @the `.marginal stitutes "a vseal which completely .joint'' between e th'efpanel `and the d positively A'prevents'any leakage -phoints vThe .marginal groove n'gueeon the' endwall-sof the cabiextended yto the bottom of the cabinet, although I have found it suilicient if they extendto a point below the top of the radiator, since there is no tendency of the air to leak below this point.

Heating units of this character are usually installed before the wall covering and flooring` are put in. It often happens, however, that the type of flooring is changed after the heat-ing units have been installed. The change in type of fiooring makes the height of the flooring a variable factor, and in order to provide for these variations the lower edge 58 of the panel is terminated short of the floor line, and the panel is provided with adjustable members 59 on the outer face thereof. In the structure shown in Figs. 1 and 4, these adjustable members are in the form of corner plates positioned against the outer face of the panel-and vertically adjustable with respect thereto, so that after the 'panel has been placed in position these corner plates may be raised or lowered to conform to the relative height of the floor liuc. It is thus unnecessary t0 individually eut or trim the panels to provide a finished joint between the panel and the floor. T he corner plates may be given any suitable shape to conform to the harmonious appearance of the panel. They are fastened in their adjustable posiI tion by instanding threaded studs 6() on which clamping nuts are threaded. These studs ex tend through slots 6l in the panel, the slots being long enough to permit relative adjustment of the corner plates and panel.

In Figs. S, 9, and l0, a modified form of adjustable panel is illustrated. Instead of using corner plates 59 as adjustable members, a baseboard eli'ect is obtained by providing a suitable member which extends clear across the width of the panel, and is provided with a cut-out 66 which coincides withthe inlet opening 49 at the lower edge of the panel. This single member is preferably shaped like a basehoard and thus harmonizes with the baseboard of the room in which the unit is installed. It is .spaced outwardly to some extent from the surface of thel panel, but is supported against the panel by the spacing member (i7 secured to the inner face of the bascboard member G5. The spacing member has threaded studs (it) which extend through slotted openings Gl in the panel and carry clamping nuts at their inner ends.

Instead of welding or permanently fastening the tongue 57 to the panel. it may be fastened thereto by Studs (3S which are mounted on the inner face of the panel and project through elongated slots 69, Fig. 10, so that the tongue member may he adjusted relatively to the panel if desired. .lhis provides an additional adjustment for the structure in the event that the variations in building construction requires a greater range of adjustment than is provided by the structure heretofore described.
